Choose menu shows up properly. But problems in the games:
Gradius: Game appears to load up properly. The sound is fine and by pressing START -> DOWN -> START, one can go back to the main menu. However, there is no display. Error message:
Gradius 2: Same as Gradius. Error message is the same as Gradius 1.
Gradius 3: Part of the game display is outside the PPSSPP window. Also missing some layers in game display (such as 1 PLAYER, OPTIONS, RETURN TO MAIN MENU in title screen
and the weapon selection boxes
). Then no display (but sound) in game. Error message is the same as Gradius 1.
Gradius 4: Playable, though show the same error message as Gradius 1.
Gradius Gaidan: same as Gradius. Error message is the same as Gradius 1.

I think there are some display issue. The emulator fails to show everything in the screen in its window for Gradius 3 and Gradius Gaiden. See in gradius3.png that there is an enemy on the top right corner but the background is not shown up. In Gradius gaiden, we see traces of previous game on the top of the screen (those things above "1P 3100 CREDITS 9"). The power meter at the bottom of the screen is missing. The screen doesn't appear to be centered properly. This degrades gaming experience.

v0.9.8-1064-g90b30f8 appears to have solved the issue in Gradius 3. The Gradius gaiden still suffers.

Please see the attached screenshots for details. Both have buffered rendering (the default setting) and simulate block transfer enabled (I need to check it under Graphics -> Rendering Mode).

The correct display behavior is shown in gradiusGaidenSoftwareRendering.png. I make it by further enabling software rendering (Graphics -> Debugging -> software rendering (experimental)) You can see that the play screen is centered properly. We have the power meter at the bottom left corner of the play screen.

But if we use the default rendering mode (i.e. not using software rendering), the screen is shown in gaiden.png. You can see the the play screen is translated a bit downward, thus blocking the bottom part of the play screen (which has the power meter) from showing.

Are you using "buffered rendering"? Any other mode is likely to have bugs. I also suggest enabling "simulate block transfers".
